が提案されている。2. Description of the Related Art The properties required of ink jet recording inks are that physical properties do not change during long-term storage,
It is required that the fine nozzles are not clogged, that the printed matter has a high density and is clear, and that the printed matter is storable (water resistance, light resistance, etc.). In particular, in the case of a pigment ink, it is required that the storage stability and the nozzle do not clog during printing or during restarting after printing is interrupted. As a pigment-based ink having these characteristics improved, JP-A-56-147 is known.

印字ムラは重要な課題となっている。However, in the above-described conventionally known pigment-based ink, both the clogging property of the nozzle and the finger touch property such that the print surface and the finger are contaminated when the print surface is touched by the finger are compatible with each other. Cannot be achieved, and as the fill of the print becomes larger, there arises a new problem that is not seen with the dye ink, that the print becomes shaded during the fill (hereinafter referred to as “print unevenness”). Although the exact cause of this print unevenness is unknown, printing was performed by increasing the pigment concentration or using an excessive amount of ink ejection to improve print unevenness, but it did not improve. It is believed that it depends largely on this. Therefore, the conventional pigment ink composition cannot achieve high-quality recording, which will be required in the future, and this printing unevenness is an important issue for use in applications in which not only simple characters but also large shapes such as figures and graphs become large. Has become.

詳細に説明する。Therefore, according to the present invention, at least a pigment and a water-soluble resin soluble at a pH of 10 or more are used.
The ink for inkjet recording is characterized by containing ˜7 wt% and sugar in an amount of 0.5 to 10 wt%, and further having a pigment / resin ratio of 1: 0.5 to 1: 2. The present invention will be described in detail below.

の凝集によって、印字ムラとの両立も可能となった。In order to satisfy the above-mentioned object of obtaining an ink having good touchability without clogging fine nozzles of an ink jet, the inside of the nozzle does not solidify but maintains fluidity, and when it adheres to paper. However, it is necessary to have two contradictory properties of not being redissolved in water or ink. The present inventors have found that the above object can be satisfied by using a resin having a narrow pH range for solubilization, that is, a resin solubilized at a pH of 10 or more in order to obtain a rapid change in PH. . In addition, it is possible to achieve both printing unevenness and ink aggregation due to a sharp decrease in PH.
